HEEL-BREASTING MACHINE.

Application filed June 13, 1919, Serial No. 303,883. Renewed October 1, 1922. Serial No. 592,397.

To all whom it may concern.

Be it known that I, LOUIS A. CAscRAIN, a citizen of the United States, residing at Beverly, in the county of Essex and State of 6 Massachusetts, have invented certain Improvements in Heel-Breasting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on 10 the drawings indicating like parts in the several figures.

This invention relates to machines for operating upon the breast portions of shoe heels and particularly to machines for forming the breast portions of Louis heels after they are attached to their shoes.

Some heels, for example Louis heels, have their breast faces curved longitudinally of the shoe and are usually breasted by moving relatively the heels and a rotary cutter transversely of the heel. It is frequently desired that the portions of the breast faces of such heels which extend heightwise of the heel be additionally curved convexly.

An object of this invention is to provide an improved machine organized to form a convex face on the heel extending height Wise of the heel by relative movement of the knife and heel transversely of the heel. Accordingly, a featureof the invention consists in an organization including shoe hold ing means and breasting means movable laterally of the heelin such manner as to form on the heel a convex face extending heightwise of the heel. Preferably two knives are provided which act from opposite sides of the heel in curved paths to form on the heightwise extending portion 'of the heel breast a surface which is" curved transversely of the breast; As shown the knives are moved about an axis located at the rear of the breast to form two convex surfaces extending from the sides of the heel toward the center of its breast and coinciding to form a surface convex toward the toe of the shoe. v

Due to the springing of the knife operating mechanism and to the difliculty of maintaining the cutting edges of the knives in accurate parallelism it is impracticable to cause the knives to meet or even substantially to meet at the center of the breast, Stlill a construction resulting either in actual contact of'the knives and'consequent dulling of their edges, or, if the knives are set to prevent contact under any conditions of work, in the formation of an unsevered fin at the center of the heel which, when the chip is torn off, produces a blemish at the center of the heel.

Accordingly a feature of the inventio consists in means for causing the-knives, upon their initial movement in the cycle, to

approach the center of the breast and then,

for causing oneknife to retract while the cutting movement of the other continues to sever the chip completely from the heel. This results in the formation of a smooth breast face by the initial action of the cutters and removes any line 'of demarcation between the surface formed by one knife and that formed by the other knife.

The base portionyof a Louis heel extends substantially lengthwise of the heel forwardly of the shoe along the shank and should be convex in form with its forward edge flush with the surface of the shoe shank.

A further feature of the invention consists in a knife shaped to form both, the height wise and lengthwise extending portions of the breast by relative transverse movement of the shoe and knife and means for relatively moving the shoe and knife, during the relative transverse movement of the shoe and knife, in the direction of the height of the heel to cause the portion of the knife which forms the base or lengthwise extending portion of the heel to follow the convex curve of the shank and to trim the forward edge of that portion flush with the surface of the shank. As shown the two knives are employed which are moved bodily during their approaching movement and in such time relation thereto as to form the base portion of the heel as described.

Since the knives have a predetermined path of movement it is essential that the shoe be accurately positioned relatively to the path of the knives. To this end a further feature of the'invention consists in stop members mounted upon arms movable laterally of the shoe in a plane extending generally lengthwise of the shoe to carry the stops into and out of position over the shoe shank, the shoe being located against the stops during. operation of the knives. As shown these stop members, when over the shoe bottom, are located beneath rigid abutments on the machine frame which prevent any vertical movement of the members by pressure of the shoe against them when the shoe is raised and positively locate the shoe vertically relatively to the knives. As shown the stop members are movable laterally out of the way of the shoe to allow free movement of the shoe longitudinally into and out of operative relation to the knives.

After the breasting operation and while the shoe is still held in the machine it is desirable to perform the operation of scalloping'the heel. This operation consists in forming a concavity in the portion of the heel breast adjacent to the top lift and is best performed by means of a rotary cutter.

Another feature of the invention consists in a rotary cutter which is arranged to move heightwise of and toward the heel to treat the heel breast. Preferably the cutter is located normally at one side of the shoe and out of the way of the shoe as it is inserted into and removed from the machine and means is provided for moving the cutter laterally and rearwardly of the shoe to locate it above the heel prior to its movement heightwise of the heel to treat the heel breast. As shown, the cutter'is frusto-conical in shape with its smaller end toward the heel. The cut formed by the cutter has therefore a larger radius of curvature at the portion adjacent to the tread face of the heel and a smaller radius where it merges into the convex portion of the breast face.

These and other features of the invention, including various novel combinations and organizations of parts, will appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed r the machine Fig. 4 is a vertical section of the head of the machine on the line %4 of Figs. 2 and Fig. 5 is a transverse section on the line 5-5 of Fig. 1. 7

In the drawings, the numeral 2 indicates the frame of the machine in the lower part of which is mounted a shaft 4 having thereon various cams, to be referred to hereinafter, by which certain parts of the operating mechanism with which themachine is provided are operated. Loosely mounted on one end of the shaft 2 is a driving pulley 6 to be driven continuously by belt connection to a source of power. A suitable clutch is provided between the shaft 4 and pulley 6 to cause the shaft to be driven through a single revolution at each depression of a treadle 8. V

The work support comprises a post 10 on the upper end of which is adjustably mounted a last pin 14. The post 10 is arranged for longitudinal movement in a jack sleeve member 20 which is pivotally supported at 21 on the outer end of a lever 22 fulcrumed to the frame at 24. The member 20 is provided with projections 26, 28 which limit swinging movement of the member on its pivot 21 inwardly and outwardly, respec' tively, by engaging the lever 22. The post 10, normally, is yieldingly sustained by a light spring. Before the machine is started the post 10 'is free to be depressed against the spring and to be swung in and out about the pivot 21. When in outwardly swung position a shoe is placed upon the pin 14 and swung toward the machine, being at the same time depressed to enable the heel to be positioned beneath a tread plate 34. Rearward movement of the shoe is limited by a back stop 36 on the plate 34 which engages the rear face of the heel. The longitudinal tilt of the shoe is determined by a rest 38 adjustably secured at 40 to a projection 42 on the frame 2 and arranged to engage the bottom of the forepart of the shoe. A similar work support is shown and more fully described in my application Serial No. 290,670, filed April 17, 1919.

It is important, as will later appear, that the shank of the shoe be located in a predetermined position vertically, and it is also important that there be no obstruction in the way of the shoe during its movement into the machine as described. Accordingly two shank stops 50, 52 are provided which move laterally of the shoe over the shank portion thereof before the jack is raised, the movement being preferably effected by a connection with the treadle 8 so that a preliminary movement of the treadle will position the stops over the shoe, and further movement of the treadle will start the machine. The stops 50, 52 are on the ends of horizontal arms 54, 56 which are loosely fulcrumed re spectively on vertical shafts 58, 60. The arms 54, 56 haveextensions 62, 64 (Fig. 3) at the rear of their pivots 58, 60 which extensions are adapted to be engaged by a wedge member 66 arranged to slide horizontally in ways formed in a part 67 secured at 69 to a stud 71 extending rearwardly from the frame. Movement of the wedge member 66 separates the extensions 62, 64 and causes the shank stops 50, 52 to approach each other and assume positions over the shoe bottom. The wedge member 66 is moved by a suitable shaft 7 0 which has an arm 72 connected to a rod 74 the lower end of which rests upon the rear end of the treadle lever 8. The rod 74 is pulled downwardly by a spring 175 (Fig. 1) connected to the rod and to a pin on the frame. It will be seen that depression of the lever preliminary to starting the machine will push upwardly on the rod 74 and cause the stops 50, 52 to be positioned over the shank of the shoe. The stop arms 54, 56

have surfaces 76, 78 (Fig. 5) whichlie bepost 10. For this purpose theblock 84 is.

mounted on the end'of an arm 86 of a rock shaft fulcrumed on the "sleeve member 20 and having an arm 88 connected by a link 90 to a lever 92 fulcrumed at 94 on the'lever 22 and held from movement by a linkfl96 which connects the lever 92 to the frame 2. The lever 22 extends into the machine frame and at its rear end has 'a link 97 which connects it to a horizontal arm 98 (Fig. 2) from a rock shaft 100 which is mounted in the frame and has a depending arm 102carrying a roll arranged to engage edge cam 104 on the shaft 4. In the'drawings the machine is represented as having been staited, the shaft 4 having moved through about 130 degrees. This has caused thearm 1Q2t0 be moved to the'left byits ,311 -lO4, elfecting a downward pull on the link"97 and causing the outer end of the lever 22 to move upwardly; During this movement the arm 86. 'Which operates the pawl 84 has been held [from movement by the 'oonnectionsdescribed and has caused the pawlblock 84 to engage the teeth on the post 10. A slight upward movement of the jack member 20-before the post 10 is locked is permitted by a lost'motion connection between thelink 90 andthe lever 92. In conjunction with the upward movement of the shoe and the shoe support, by reason of its connection with the outer end of the lever 22, there is ,a downward movement of the tread plate 34 which is,

effected as follows: The" tread plate 34 (Fig. 4) is mounted on the front end of a lever 106 fulcrumed at 108 at the rear of the machine and having connected thereto between its ends a rod 110 the lower 'end of which is connected to the rear arm of the lever 22 at 112 (Fig. 1). Downward movement of the lever 106 is effected yieldingly' through a spring 114' (Fig. 4) arranged between the lever 106 "and a nut .116 'on'the end of the rod 110. The lever 1 .06 islifted by a collar 115 on the rod 110. -When the machine starts, the jack will be raised a predetermined amount determined by the cam';104 to force the shoe against the shank stops and t moveme t il f rce the shoe with equal pressure against the shank stops 50, 2

since the variation in the heights of lasts is 2 taken care of by the relative movement of the post and sleeve before the locking paw .84 op ates to preve suc r tive ovement- The mach is provided Wi tw breast. ring knives 120 and 122 which operate from h sid f he heel towar h oenterio -thle contour on the portion of the breast face hextend h ig tw s of he heel, are ar-.

the Other from a sleeve 130 surrounding the s ft 124! The s e e 130 has keyed theret a segmental gear 134 meshing With L similar segmental gear 136 pinned to thecshaftfil).

The shaft 124 has fixed thereto a segmental gear 138 meshing with a segmental geafrl secured tothe shaft 58. Qbviously -rooking movement of the shafts 58, .60 in opposite die rections willcause the knives to approach each other and to move in a curvedpath across the breast face of the heel. To effect operation of the shafts 58, they are extended downwardly through suitable bear:

ings and providedat their lower ends (Fig. 2)- with arms 142, 144 carrying cam rolls which engage separate cam paths 148; 145 (Fig. '1) formed .in a cam block 146 on the shaft 4.

Since the shank of a shoe is transversely convex, it is important to effect relative movement of the knives and shoe heightwise of the heel as the knives approach the centerof the heel breast from the two sides order to give the base portion of the heel which extends substantially lengthwise of the shoe an upward convexity which corresponds at its forwardedgeto the curve of the shank and merges into the convexity extending heightWise of the heel and formed by movement of the knives about the axis ofthe shaft 124 and sleeve 130. In the 'construd tion shown theknives are arranged tofbe raised as they approach the center of the each other. To'effect this the shaft 124 and sleeve 130 are mounted for turning move ment in a slide 148 guided for vertical moveeel and wh ch, in o de to f rm a convex v.3"-

required vertical movement of the segments 134, 138 without disengagement of the segments.

It will be clear that the knives should not meet in the center of the heel since it would be impracticable so to adjust the knives that they would approach closely enough to make a clean out without sometimes coming in contact. Moreover, if the knives are adjusted so that there is a substantial space between them, although the chip might be torn off, it would produce a tin or rough place at the center of the heel which it would be difficult to remove in the buffing operation. Thesediificulties are overcome in the present machine by a construction which causes the knives to approach each other and nearly to meet at the center of theheel but not to approach sufficiently close to cause the chip to break off. Then, following this initial movement, the movement of one knife is arrested and its retraction begun while the movement of the other knife is continued sufficiently past the center completely to sever the chip. This result is effected by suitably designing the cam paths 143, 145 in the edge of the cam block 146 to cause the movement of the knives to take place as described.

" After the shoe has been breasted'in the manner described, it is desirable to scallop the heel and in the construction shown antomatic means for effecting this operation is provided. A frusto-conical cutter 162 is arranged normally above the shoe and at one side of its longitudinal median plane so as I v the COIDblllfltlOlT of cutting means constructto be out of the way of the shoe as it is swung into the machine. Means is provided for moving the cutter laterally and rearwardly of the shoe to a position over the breast portion of the toplift of the heel and causing it to descend into engagement with the heel to form the scallop. The cutter- 162 is on a vertical shaft 164 (Figs. 3 and 4) having at its upper end a pulley 166 from which a belt 168 passes over idlers 170, 171 loose on ashaft 172 and around a pulley 173 on a counter shaft 174 (Fig. 1) On the opposite end of the counter. shaft is a pulley 17 5 connected by a belt'176 to a separate crowned surface on the constantly driven pulley 6. The shaft 164 haspearings in a vertically movable slide 180. The slide 180 is mounted in a segmental shaped menuher 182 which in turn is mounted in curved about its center of curvature.

guides 184 formed in a part- 185 fixed to the frame so that the member 182 may move An arm 186 fixed to the member'182 is connected by a link 188 to an arm 190 of a rock shaft 192 journaled in the frame and having an arm 194 connected-by a link rod 196 to a lever 198 fulcrumed at 200 to the machine frame and carrying a cam roll 202 which is acted upon by a cam path 203 in the front face of the cam block 146 which causes, through the connections described, the'arm 190 to be moved to the left (Fig. 2). This effects movement of the segmental member 182 about its center of curvature (Fig, 3) to carry the cutter shaft from itsinitial position forwardly of and at one side of the heel into position over the toplift of the heel. The link 188 has universal joint connections at its ends to the arm 186 and to the arm 190 respectively. The slide 180 is next moved downwardly to cause the cutter 162 to operate upon the heel and this is effected by means of a lever 204 fulcrumed at 206 to the machine frame and having at its forward end segmental teeth to engage corresponding teeth 205 on the slide 180. At its other end the lever 204 is connected by a rod 208 to a lever 210 fulcrumed at 212 to the machine frame and having between its ends a cam roll 214 which engages a cam path in the rear face of the cam block 146 suitably designed to effect, at the proper time in the cycle of the machine, a downward movement of the slide 180 to cause the cutter 162 to effect the scalloping operation. The teeth 205 on the slide 180 are extended concentrically' 'wi th the curve'of the segmental member 182-to permit turning of the segmental member and the slidewithout dis engaging the teeth 205 from the end of the lever 204.
